posedbetween they center sills or ydraft sills`v of zu railway car to/provide means for receivingthe bufling shocks to which the rigging is subjectedv in service, and transL mitting them to the lcar underframe.

The principalobiect ofthe invention is to provide a strong, durable and simply constructed-back stop inwliich the 'maximum strength. value of the related parts: is obtained with theminimum use of material, thereby providing a comparative-ly lightweight back stop which. can be vreadily at'- tached to the carsills with small vexpenditure of labor.

The principal fea-tune lofthe invention,` generally stated, consists 1n forming a backl stop with. side walls'adapted tobe' connected tothe. .can sills andv withthe forward end wall integrally united-to saidesid'e walls andV arranged toforman abutment for' a movable part of the draft rigging, and' in bracing and? supportingv said endwall vby means of intersecting horizontal and vert-ical' webs united at their forward ends to the end wall and said side walls.

` A further object ofthe invention consists in providing the back] stop with side walls and with an end wall constituting` an abutment for a movable Y'part ofthe draft rigging,y and in providing bracing nie-ansi for thel end wall, said bracing; means including a transversely disposed horizontalV web or ange-.uniting the end abutment of the side walls, said'horizontal' web being formed with reinforcing .longitudinally disposed vribbed portions. y y Y A further feature ,of myinventionvconsistsv in providing the back stop' .with side walls and an endwall constituting an abutment for a movable part of the draft rigging, said end fwall being bracedv against bufling shocks by means of a. transversely arranged flange including an invertedv I, Gusfnir A.

Q'ther featuresof theA invention residing in' the'construction and arrangement of theV structural parts, will hereinafterl appear.

In' the drawings illustrating the invention, the sco-pe whereof'is pointed out inthe claims?l Vliligurlevl isa view partlyin plan and Y partly `in horizontal'` section of a lportion of the vcenter sills ordraft sills of a railway car showing, a baclr'stop involving the' in'- vention applied' thereto', a portion of' the;

4 Figure, 8 is a vertical longitudinal sectionalview :through the back. stop illustrated in. Figure 7. l

Referring tothe. drawings in which sim: ilar reference characters designate corresponding parts in the several views and more particularly to Figure 1, I have shown my improved back stop 1 interposed between and connected to the center sills or draft sills 2-2 by means of rivets 3. The rear end of the yoke 4 is cooperatively associated with the back stop, the cushioning mechanism of the draft rigging being diagrammatically indicated by the dot and dash lines.

rlflie back stop 1 is formed with longitudinally extending side walls 5 adapted to engage the inner faces of the adjacent car sills, each side wall being provided with a plurality of spaced horizontally extending rows of openings for receiving the attaching rivets 3 whereby the structure can be firmly connected to the car sills.

The end wall 6, positioned so as to be termed the forward end wall herein, is integrally connected to the side Walls 5, and is adapted to afford an abutment for a movable part of the draft rigging in resisting builing shocks. The outer ends of the side walls are preferably curved at the corners and the outer side portions of the end wall 6 are slightly inclined as at 7, said inclined portions joining the end wall, as shown, to provide a maximum centrally located buffing face on said end walls 6.

A transverse flange or web 8 unites the side walls of the casting, and also the end Wall 6 and the closed upper end of the center thimble 9. This transverse wall is of irregular contour, it being shown in the present embodiment of my invention as comprising a centrally inverted U-shaped or channel portion, the top part 10 thereof being arranged in a higher horizontal plane than the portions 11 of said web or flange. The horizontal portions 11 join the vertical flanges 12 of the channel portion, the vertical flanges extending below the plane of the web portions 11, as clearly shown in Figure 4. The upper portion 10 of the inverted U-shaped channel is forwardly and upwardly inclined, as shown in Figure 2, and is designed to join the forward end wall 6 at a point near the upper edge thereof. The irregular forming of the transverse flange or web 8 whereby portions thereof lie in different or varying planes, permits of the ready insertion of the rivets through the intermediate row of openings. In addition, it will be obvious that means of a greater reinforcing value can be centrally located in the rear of the forward end wall to absorb the direct shocks through the rear of the yoke.

The vertical reinforcing flange or web 13 is designed to brace the forward end wall 6, said flange being located centrally and longitudinally of the casting and uniting the forward end wall 6 to the center thimble. The vertical flange 13 also intersects the portion 10 of the inverted Ui-shaped channel formed in the transverse flange, and

unites the top portion 14 of the casting with the base plate or floor portion 15 thereof. The portion of the vertical flange beneath the transverse web is indicated by the numeral 16, said portion adjoining the base plate 15 and being cut away as shown. The portion above the transverse flange is indicated by the numeral 17, said portion constituting a longitudinal rib joining the top portion 10 of the U-shaped channel.

rlhe base plate or floor portion 15 of the casting is preferably cut away, as indicated at` 18, and is providedj adjacent its side edges with inclined portions 19 which latter are designed to overlie and conform to the adjacent flanges of the center sill or draft sills- The side walls`5 are preferably extended rearwardly and offset from the horizontal, said extensions terminating in stop niembers 21 between which is arranged an end wall or abutment 22 of relatively smaller size and less height than the end wall 6 described liereiii as the forward endwall. The

end wall 22 is braced by means of a plurality of longitudinally alined ribs or flanges, the central flange 23 lying parallel to the side walls 5, and the web or flange 24 being slightly inwardly inclined from the center thimble as best shown in Figure 1.

end wall 22 at or about the junction of the inwardly inclined flanges 24 and said end wall.

A horizontal or transverse flange or web 26 connects the extensions of the side walls, said web intersecting the vertical flanges or webs 23 and 24, as clearly shown in Figure 3, thereby forming substantially a ribbed reinforcing means for said transverse flange. rlhe stop portions 21 are braced by a plurality of longitudinally arranged ribs 27, said ribs serving to unite the end wall extensions and said stop portions. The intermediate ribs are joined by the obliquely ldisposed flange 25.

The portion of the base plate on the side of the casting` just described is cut away as shown, extending stop portions of the casting serving as guiding means in some cases for portions of the draft rigging mechanism. The transverse vertical web 28 unites the side wall members intermediate the re- Il l) spective end walls of the casting, said trans-y verse vertical wall intersecting the center thimble. l Rivetop'enings 29v are formed in bined kback stop andl center filler member in whichan advantageous arrangement of the integrally oined'flanges or.A ribs servesto ef'- fectively resistbulling shocks orblows and transmitl them to the associatedcar fran'iing without distortion. ory deformation ,of the casting. I provide -insubstance a centrally locatedy channel or U-,sliaped portion `with the respective portionsfof the transverse flange in varying planes upon either side of the intermediate vertical vweb 28, so as to provide space fortlie insertion of the intermediate row of rivets, and t-o alsoprovide for increased. bracing means adjacent the forward end wall 6. V

vIn Figures and 6 of-tlie drawings, I have shown a modified form ofthe linvention in which the centrally located' channel or U-,shapedportion of the casting is formed with inwardly converging vertical flanges 30, said flanges'uniting the center thimble 31 to the forward end wall 32, as shown. Similarly, the uniting. the opposite end ter thimble 31 are also inwardlyinclined tolward thev center thimble, the said opposite end wall 34 being shown straight and transversely connecting'the side walls of the cast ing. Diagonal portions 35 serve to brace the extensions 36 of the side wallsan'd the opposite end wall 34. A transverse vertical web 37 unites the side walls intermediate the opposite end walls,

verse wall intersectingthe centerthimble, as sliown.

The modified forin'of back stop castingsliown in Figures and 8 includes a channel or U-sli'aped portion 3S' adapt'ed'to brace the forward end wall 39, the inner ends of the channel portion terminating and uniting tl e intermediate transverse verticalI web 40 with said end wall, as in the -pieferredembodiment as hereinbefore described, The side vertical flanges or ribs of the U-sliaped channel portion arey thisulpresent niodilication parallel with the side walls, as shown. rPhe opposite Vend walll 41 is rshown as straight and transversely connects the side A horizontal trans-V walls of the casting. verse flange 42 is provided on the .upper and lower faces thereof with verticalribs or flanges 43, said ribs being arranged inparallel with the side walls ofthe casting. and uniting the upper portions 44a-nd the lower base plate portion45, as clearly shown-in Figure 8. Diagonal bracing webs 14,6 .unite the sidewall extensions and the oppositev end wall 41.

.lt will be apparentthat vertical -ribs or Hanges 33 Y wall 34 to the censaid vertical transby means of the internal''flangesl and ribs provided on a bacll stop constructed in accordancel with my invention, that the castingv is so reinforced that' all stresses to which it may besub'jectedv in'v service 'are amply resisted by sullicient sections of metal s o economically arrangedthatr the casting, while possessiiiggreat strength, is comparatively light' in weight and is, moreover, a simple casting bothV to mold and cast.
